<span>Pollination is when the male gamete or pollen reaches the female flower through different modes...wind,air,animals,...
Fertilization </span><span>is when the male gamete "join" with the female gamete to become an embryo.
I hope I helped.:) </span>
Answer:
The magnitude of the magnetic field is 1.01T and its direction is in the negative x direction
Explanation:
In order to calculate the magnitude and direction of the magnetic field, you take into account the following equation for the magnetic force on the proton:
(1)
v: speed of the proton = 9.9*10^5 m/s
q: charge of the proton = 1.6*10^-19C
B: magnetic field = ?
FB: magnetic force on the proton = 1.6*10^-13N
When the proton travels in the positive y direction (^j), you have that the proton experiences a force in the positive z direction (+^k). To obtain this direction of the magnetic force on the proton, it is necessary that the magnetic field points in the negative x direction, in fact, you have:
^j X (-^i) = -(-^k)=^k
To obtain the magnitude of the magnetic field you use:

The magnitude of the magnetic field is 1.01T and its direction is in the negative x direction

Answer:
the electromagnetic force
The momentum is calculated by multiplying the mass and the velocity of the object.
momentum 1 : = (10 g)(4 m/s) = 40 g m/s
momentum 2: = (1000 kg)(0 m/s) = 0 kg m/s
Thus, the paper airplane has a greater momentum than the real airplane.
